The THEMIS FGM benefits from long-term experience in the design of ring cores and sensors. Tests and calibration have been performed in high-precision facilities developed for a number of previous missions. The FGM uses an updated technology developed in Germany that directly digitized the sensors' signals and replaces the analog hardware by software. Use of the digital fluxgate technology results in lower mass and improved robustness. Technical University of Braunschweig, (TU-BS), Germany.

The five spin-stabilized (spin period = 3 seconds) THEMIS probes carry the comprehensive packages of plasma and field instruments needed to determine the cause of geomagnetic substorms. The instruments being flown are:. Electric field instruments (EFI). Search coil magnetometers (SCM). Solid state telescopes (SST). All-sky white light imagers (ASI). Digital Fields Board (DFB)-Filter Bank (FBK)-Fourier Power Spectra (FFT). On-board Spin Fits (FIT) from EFI and FGM Instruments. Data Policy and Credits.

Stage 42: Dayside Science Phase, HSO Optimization with MMS and VAP. In the dayside science phase the apogee of P3, P4, and P5 are approximately 12 Re. The probes are separated by 1000 km to a few Earth radii at apogee. MMS is at opposition in the tail. THM-MMS on resonant orbits, to study dayside-nightside reconnection simultaneously. Stage 41: Dayside Science Phase, HSO Optimization with MMS and VAP. Stage 40: Dusk Science Phase, HSO Optimization with MMS and VAP. In the tail science phase the apogee of...

The THEMIS Digital Fields Board (DFB) performs the spectral processing for the Electric Fields Instrument ( EFI. And the Search Coil Magnetometer ( SCM. The resulting data represent the electric and magnetic wave power in bands from DC up to 8 kHz, plus a high-frequency electric field band from 30 kHz to 500 kHz. Additionally, the DFB filters and digitizes the analog signals from the EFI and SCM instruments. Laboratory for Atmospheric and Space Physics (LASP). University of Colorado, Boulder.
